Since the first solar panel cast its shadow at dusk, humanity has wrestled with a deceptively simple question: where does the sun go when we need it most? Researchers at UC Santa Barbara may have found an answer not in larger batteries or better grids, but in the architecture of molecules themselves — engineering a pyrimidone-based material that locks sunlight into chemical bonds and releases it as heat on demand, outperforming lithium-ion batteries in energy density and successfully boiling water using only stored solar energy. The breakthrough reframes solar storage as a chemistry problem ra
